While a few years ago you could land a good job and run it for the majority of your life, nowadays we all live in a continuous update cycle. We need to constantly change to keep up with the world, otherwise we are left behind.
This is a necessity. And, since it's not a viable idea to land a lifetime job, why not turn yourself into a one man company, running your own freelancing business?
The gig economy is exploding. Small and big companies are always looking for reliable, skilled and flexible people for a short term cooperation.
Sure, short term is short term. But it can be extremely well paid and very profitable.
And, in the gig economy, you're not restricted to a single client: you can work with multiple clients, building a reliable business on top of your passion - and be paid extremely well to run it.
